Hi, I am converting a freshwater tank to brackish (1.005 or so) which currently contains Violet Goby, Guppies, Ghost Shrimp, Mystery Snails and Ramshorn Snails. My only real query is on the snails, can they adapt and survive in this environment? I also have a batch of Mystery Snail eggs on the inside of one of the lids, would the young survive (it can be moved - just wet the surface you want it to stick to and it'll stick). I have two other Freshwater tanks, all with these helpful snails (one of the other tanks also has Malaysian Trumpet Snails), so moving them out of the to-be-Brackish tank is no problem. Thanks for your help... Tim.
